Specializes in Dermatology

Allergic reaction: Patch testing is done when there is a reasonable suspicion that the dermatitis is caused by an allergen that is contacting the skin (allergic contact dermatitis). It can be quite valuable but requires a very thoughtful clinician and a carefully done history.
